Everytime I turn off my Macbook (as in shut it down rather than just close the lid), and consequently my Firefox logs out of my account automatically, my extensions, dictionary (as in British rather than US spell checks) and search preferences seem to reset, meaning that every time I log in to Firefox I have to re-configure my preferences. Only my bookmarks seem ti save between uses. This isn't really a big deal, but I don't think this is how it is supposed to work? How do I save my preferences between log ons and offs? Thanks!
